The autogyro is being investigated for potential use as a small unmanned air vehicle for Navy electronic warfare missions. This paper presents wind tunnel test results for a 42 inch diameter unpowered rotor with coupling between feathering and flapping that allows for self-starting from a vertical descent. Aerodynamic performance is given for several blade pitch angles and angles of attack. Autogyro, Rotor, Rotary-wing

This report and its lengthy appendix first reviews early autogyro history. The period from Juan de la Cierva's invention in the early1920s through to the U. S. Army Air Corps' choice, in 1943, of the helicopter instead of the more fully developed autogyro, is examined from a technical point of view. With this historical background in hand, simple aerodynamic technology for rotors, wings, propeller, and fuselages is provided for reference. The McDonnell XV-1 convertiplane development and its...

The interrelations established in an earlier report (NACA-TM-921) are used to study the best assumptions for hovering and horizontal flight. The effect of the twisted and tapered blade on the rotor efficiency is analyzed and the gliding coefficient at different stages (from autogyro to helicopter) of horizontal flight compared. To the extent that model or full-scale test data are available, they are included in the comparison.

To increase aircrewmen's chances for safe rescue in combat zones, the armed forces are investigating advanced escape and rescue concepts that will provide independent flight after ejection and thus reduce the risk of capture. One of the candidate concepts is discussed; namely, a stowable autogyro that serves as the crewman's seat during normal operations and automatically converts to a flight vehicle after ejection. Discussed are (1) the mechanism subsystems that the concept embodies to meet...

The report describes the design and development of an air droppable weather station (the AN/AMQ-27( ) Meteorological Station, Automatic). The Station grew out of a requirement for meteorological measurements in hostile or inaccessible areas. The Station's deployment vehicle mimics an autogyro when dropped from an aircraft. The main rotor blades control descent rate, while a set of counter rotating blades provide vertical stability. Upon touchdown, the impact spear embeds itself in the earth,...

This report describes a simple decelerator which drives a submunition in a lunar motion while it descends vertically over a battlefield, scanning for armored targets. The decelerator consists of a single flexible fin with a weighted tip. The idea of using a flexible fin with a tip weight to generate a lunar scan motion was derived from the flight of maple seeds or samaras. Aerodynamic testing consisted of flying various configurations of the submunition in a vertical wind tunnel during which a...

The subject of this paper is milestones in rotorcraft aeromechanics. Aeromechanics covers much of what the engineer needs: performance, loads, vibration, stability, flight dynamics, noise. These topics cover many of the key performance attributes, and many of the often-encountered problems in rotorcraft designs. A milestone is a critical achievement, a turning point, an event marking a significant change or stage in development. The milestones identified and discussed include the beginnings of...

The chief defect of the investigations up to now was the assumption of a more or less arbitrary "mean" drag coefficient for a section of the blade. This defect is remedied through replacement of the constant coefficient by a function of higher order which corresponds to the polar curve of the employed profile. In that way it is possible to extend the theory to include the entire range from "autogyro" without power input to the driven "helicopter" with...

This film, a silent home movie, shows a serious plane crash at the Chicago National Air Races in 1930, Trimotor stunts, and more. The film begins with images of downtown Chicago, Illinois at night. The Central United Bank tower is seen as well as other landmarks. At the 1:20 mark, the National Air Races grandstands are shown, and at 1:50 a man -- possibly organizer Cliff Henderson, addresses the crowd. At 2:24, Army and Navy aircraft fly over the crowd. At 3:45, you will see biplanes...

Five analytical tools have been used to study rotor performance at high advance ratio. One is representative of autogyro rotor theory in 1934 and four are representative of helicopter rotor theory in 2008. The five theories are measured against three sets of well documented, full-scale, isolated rotor performance experiments. The major finding of this study is that the decades spent by many rotorcraft theoreticians to improve prediction of basic rotor aerodynamic performance has paid off. This...

This “Yesterday’s Newsreel” 1950s TV show (episode 40) offers the viewer “television highlights of the news of yesteryear” by providing vintage clips of famous people and events from the first half of the 20th century. The film begins with “1901-1949: A New World Power,” an overview of the rise of broadcast radio. At Rocky Point, New York ( 00:37 ) in 1933, Guglielmo Marconi—inventor of the radio—and David Sarnoff—American radio and television pioneer and protégé of...

The report presents the technical status of the rotor/wing concept of a stopped-rotor helicopter configuration. The configuration presents attractive performance characteristics for a high-speed VTOL aircraft. The ability to predict aerodynamic performance characteristics in all flight modes is substantiated by wind-tunnel tests. A major technical problem of 3-per-rev oscillating loads on the rotor/wing pylon was minimized by the effective use of cyclic blade pitch during the high-advance-ratio...

Wind tunnel tests of a rotor/wing model were conducted for three purposes: To compare the results of testing the same model in a small and a large wind tunnel; to investigate rotor/wing planform effects on performance and flying qualities; to investigate in detail the low rotor speed range of conversion. The data gathered from testing the 7-foot diameter model in the 8- by-10-foot tunnel and in the 30-by-60-foot tunnel were in good agreement for rotor advance ratios greater than 0.15.

Made in the 1950s by the Shell Oil Co., this film "History of the Helicopter" features a look at the revolutionary machine that, at the time the film was made, had only recently come into wide use. The film features a brief look back at some of the failed attempts to build a helicopter, and discusses Breguet, Sikorsky, Berliner and others who were convinced that rotary wings were the answer to the problem of flying. The film also shows the autogiro, a relative of the helicopter....
